In order to be compatible with different welded parts, the rotating table is often designed in a modular way, and in order to increase the stability of rotation, it is also flattened. When replacing the rotating table, especially for the rotating table with the clamping mechanism set in the middle, the connection and disconnection with the power input shaft becomes quite troublesome, and the operation process is very inconvenient. Utility Model Content

[0005] In order to overcome the technical problem of inconvenient connection and disconnection between the turntable and the power input shaft in the prior art; one purpose of the utility model is to provide a motor direct-driven welding turntable, by arranging a positioning plate at the lower end of the turntable that can be quickly engaged with the motor shaft, the operating position is located at the outermost periphery of the turntable, which is convenient for disassembly of the turntable.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a motor direct-driven welding rotary table, comprising a driving plate, which is horizontally arranged and whose middle part is fixed on the output shaft of the motor; a linkage groove, which is arranged at the lower end of the rotary table, and the width of the linkage groove is the same as the width of the driving plate; a positioning plate, which has two positioning plates and is symmetrically distributed on both sides of the driving plate; the positioning plate is slidably connected in the linkage groove and can be optionally abutted against the outer wall of the driving plate; an anti-slip plate, which is arranged at one end of the positioning plate facing the driving plate and can be optionally abutted against the lower end of the driving plate; wherein, locking blocks are respectively connected with the two positioning plates in a longitudinal sliding manner; the locking blocks can be optionally engaged with the rotating table.

[0007] When the positioning plate abuts against the outer wall of the driving plate, the anti-slip plate abuts against the lower end of the driving plate, so that the rotating table and the driving plate are fixed circumferentially, and the rotating table can be prevented from being lifted up when the welded parts are taken, thereby increasing the stability of the installation.

[0008] Furthermore, the motor and the rotating table are respectively arranged below and above the workbench; a bearing is arranged at the upper end of the workbench; a plurality of sockets are arranged at the upper end of the bearing, and the sockets are evenly distributed along the circumferential direction; a plug column is arranged at the lower end of the locking block, and the plug column can be selectively connected with each of the sockets.

[0009] The bearing supports the four sides of the turntable, preventing eccentric sagging caused by uneven weight distribution above the turntable, improving the stability of the turntable during rotation, and further improving the accuracy and quality of welding. The plug post is relatively fixed to one end of the bearing to reduce the wear of the turntable.

[0010] Preferably, the outer wall of the bearing is tangent to the outer wall of the rotating table.

[0011] The bearing can also prevent parts and dust from entering under the rotating platform; when the positioning plate is pulled outward, it is convenient to lift the rotating platform upward.

[0012] Furthermore, a through hole is provided on the side of the upper end of the positioning plate away from the driving plate; a sliding column slidably connected to the through hole is provided at the lower end of the locking block; the plug column is provided at the lower end of the sliding column; and the diameter of the plug column is larger than the diameter of the through hole.

[0014] The bearing is a standard part, which reduces the difficulty and cost of processing.

[0015] Furthermore, a card block is provided at the lower end of the locking block; a card slot for accommodating the card block is provided at the upper end of the rotating table; an inclined surface for driving the card block to slide upward is provided at the upper end of the rotating table; the inclined surface is located on the side of the card slot away from the driving plate.

[0016] When the positioning plate slides toward the driving plate, the inclined surface drives the locking block to slide upward, thereby causing the locking block to enter the locking groove to be fixed, thereby further simplifying the installation steps of the rotating table.

[0017] Furthermore, two notches are provided on the outer periphery of the rotating platform for accommodating the locking blocks respectively; the two notches are respectively located at two ends of the linkage groove; and an end of the locking block away from the driving plate is provided with anti-slip grooves.

[0019] When the card block is located in the card slot, the driving plate and the rotating table are relatively fixed, and the locking block is located in the notch, and the rotating table has a smooth appearance, which prevents the operator from bumping during operation.

[0020] Specifically, a stepped groove is arranged on the upper end of the positioning plate; and two guide posts which are respectively slidably connected with the stepped groove are arranged in the linkage groove.

[0021] Specifically, a coupling is provided at the lower end of the central position of the driving plate; and the outer diameter of the coupling is equal to the width of the driving plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The output shaft of the rotating table and the motor are directly fixed, and no additional transmission or reduction mechanism is required, which has a simple structure and low cost.

[0024] 2. It has a quick disassembly structure, and the operation position is located on the outer periphery of the turntable. Even if there is a clamping and positioning mechanism on the upper end of the turntable, it will not affect the fixation of the turntable.

[0025] 3. When the positioning plate is located on the inner side, it fixes the turntable. When the positioning plate is located on the outer side, the turntable can be conveniently lifted up with the help of the positioning plate, making it easier to take and place the turntable.

[0026] 4. The locking block can lock the positioning plate and the rotating table and the bearing at the same time to prevent the relative movement between the rotating table and the bearing from causing wear to the rotating table. The locking can be completed by simply pushing the locking block inward, which further simplifies the installation steps. BRIEF DESCRIPTION OF THE DRAWINGS
